Subject

First I will create container block by using command:
php bin/console sonata:page:create-block-container default content_bottom "Left test content”.
During trying to edition this block I got error: I got error: Could not load type "choice": class does not exist. I spent some time look for some place where is not using FQCNs but I didn't found. I change type from choice to 'Symfony\Component\Form\Extension\Core\Type\ChoiceType' in FormFactory during debug code but the result will be next Exception: "Expected argument of type "object, array or empty", "string" given"
Symfony\Component\Form\Exception\UnexpectedTypeException:

Steps to reproduce

1. Create container block.
2. Go to page in admin panel.
3. Click block list.
4. Click on created block.

Expected results

Form to edit block.

Actual results

Got error: Could not load type "choice": class does not exist.

Can you try and upgrade to newest version of block bundle? It was released yesterday and it should fix this.

[michalwroblewski]

Yesterday release resolved problem with: "'sonata_type_collection". Current I use version 3.12.1. Check too 3.x-dev. But on this versions problem appear. I could not found the place where the option choice is connect with field type.

I had similiar issue. I changed this snippet for enabled: true to fix it.
sonata_core: form: mapping: enabled: false

[jordisala1991]

It would be nice to know where is the 'choice' type. What type of block are you editing?

[michalwroblewski]

Change enabled: true fixed the problem with "choice" error.

But during edit block a get new error:

On page I have three block. Every one in associate with template: sonata.page.block.container content_top etc. I found on https://sonata-project.org/bundles/page/3-x/doc/reference/getting_started.html information:
When the SonataPageBundle renders this container, it will automatically insert a sonata.page.block.container with the name footer_left if it does not exist yet. You will then be able to add new child blocks to it in the frontend. The second parameter is the name of the page. It can be either a string, or a Page instance. In case of a string, it will create a new page with that name if it doesn’t already exist.

Other way to create container block is command: php bin/console sonata:page:create-block-container default content_bottom "Left test content".

During edition I have the same error.

[michalwroblewski]

I some situation method PropertyPathMapper receive in mapDataToForms
$data == @SonataPage/Block/block_container.html.twig.
It have result in exception because the condition if (!$empty && !is_array($data) && !is_object($data)) expect Object or Array.

[jordisala1991]

IMO we should focus this issue on the bundle we have the error.

You should close this one, because everything you said so far is related to page bundle. And open the issue there. Wdyt?

[jordisala1991]

There are not a lot of places where I can find choice as string...

But I found some, I dont think it is related but probably should be fixed too:
